[Touch-packages] [Bug 1402194] Re: PCI/internal sound card not detected
A further observation today: Turning the laptop on from cold, the speakers appeared in the Sound pane as expected. When testing the Videos app, the sound played normally at first but a few crackles were heard. This seemed to have coincided with setting the display to Full Screen. The sound from the speakers then disappeared completely. On executing a restart, there was nothing listed in the Play sound through pane. After two further restarts, the Built-in Speakers were listed but accompanied by settings for HDMI/Video port showing options of HDMI sound. This persisted after another restart. I turned on a pair of Bluetooth headphones and these subsequently appeared in the Play sound through panel with options for Telephony Duplex (HSP/HFP) or High Fidelity Playback (A2DP) being offered. The Test Sound button payed the test signal correctly through the headphones. When re-selecting Speakers, Built-in Audio, the correct Settings for Speakers (Balance and Greyed-out Fade and Subwoofer) appeared. The Test Sound button allowed the left and right speakers to be tested as normal. This suggests that the kernel loses its connection to the speakers which is not necessarily reset on restart. However, the operation of switching between Bluetooth headphones and the speakers does seem to restore the connection and the correct functionality. I should be happy to test out the latest kernel software but I need advice as to how to do this (files to download and commands to execute via terminal) if anyone is able to help on this. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1402194 Title: PCI/internal sound card not detected Status in alsa-driver package in Ubuntu: Incomplete Bug description: This bug relates to the internal sound hardware in a Dell XPS 13 laptop.

[Touch-packages] [Bug 1402194] Re: PCI/internal sound card not detected
Just another observation: switching back and forth between Speakers and Headphones sometimes puts the headphones into the Telephony Duplex mode. Even though the High Fidelity Playback seems to be selectable, the Test Sound button only results in the Mono test being offered. A workaround is to turn off the headphones in the Bluetooth drop-down panel and then turn them back on. The headphones then re- appear in the Play sound through list with the Settings for Headset showing High Fidelity Playback and the Test Sound button allowing testing of right and left hand channels. (If the Telephony Duplex mode is selected, the Test Sound button allows Mono testing as expected.) This further suggests that the kernel is not necessarily recognising the full features of the Bluetooth headset every time that they are selected. (Whilst writing this, I am continuing to monitor the sound output of the Videos app. It appears to be stable without any interference from the Firefox Web Browser!) Also, the laptop has warmed up since the previous report when it was switched on from cold. Hopefully the hardware is not sensitive to temperature. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1402194 Title: PCI/internal sound card not detected Status in alsa-driver package in Ubuntu: Incomplete Bug description: This bug relates to the internal sound hardware in a Dell XPS 13 laptop.

[Touch-packages] [Bug 1402194] Re: PCI/internal sound card not detected
Another observation to add to the above. I switched on the laptop from cold. It seemed to boot up correctly and the Speakers (Built-in Audio) were showing in the Play sound through panel of System Settings Sound Input. I started to play a video through the Videos app and noticed a slight crackling, the sound playback becoming intermittent. I then switched on a pair of Bluetooth headphones and, since Bluetooth was on by default, the headphones immediately connected and started playing the sound track. I then looked at the System Settings Sound Input panel and found that, although the Headset was listed under Play sound through, they were not highlighted; the Speakers remained highlighted instead even though the sound was coming through the headphones. Using the trackpad to click between the two caused the sound output to be switched between Speakers and Headset. (The sound playback has remained clear and free from crackles since then and continues to play correctly whilst I am typing this comment using Firefox web Browser.) The mystery deepens. Perhaps someone who understands the kernel operation knows where the bug lies.

Since accepting an upgrade to the latest Ubuntu Extra software today, the Systems Settings Sound Output no longer show the internal speakers, despite numerous attempts to shut down and restart. Before accepting the upgrade, the sound played normally through the speakers. Having upgraded the system from the Ubuntu 12.10 originally installed with the laptop and finding comments relating to the software drivers for the Intel WiFi and Bluetooth chip (Intel AC 7520) and touch screen, I tried out an installation straight from a Ubuntu 14.04 bootable USB stick. The system worked well enough without these drivers so I went ahead and replaced the whole installation from the USB stick and subsequently accepted the upgrade to 14.10. I tried plugging in a headset and this produced a screen allowing me to select the type of headset (mono, with or without mic or stereo). An extra entry appeared in the System Settings Sound Output pane allowing me to choose between the headset or the speakers and to test the audio on each one. However, unplugging the headset seemed to produce intermittent behaviour, the system being uncertain as to whether the headset was in use.

[Touch-packages] [Bug 1402194] Re: PCI/internal sound card not detected
Just to add even more complication to the issue: Having restarted the system yet again, I find that the Sound Output pane is now showing the Speakers, Built-in Audio under the Play sound through list. The Test Sound button now works as expected and the Fn-F11 F12 keys control the Output Volume slider (producing the adjustment pop from the speakers into the bargain). The problem really is one of intermittent detection and operation of the sound hardware. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1402194 Title: PCI/internal sound card not detected Status in alsa-driver package in Ubuntu: New Bug description: This bug relates to the internal sound hardware in a Dell XPS 13 laptop.

[Touch-packages] [Bug 1402194] Re: PCI/internal sound card not detected
The sound system has now taken on a new personality of its own. The internal speakers appear in the Play sound through list of Output pane of System Settings Sound along with Headphones, built-in audio (even though there are no headphones connected. The Test Sound button works on both these items but produces the same test through the internal speakers. The Rhythm Box Music player produces sound out of the built-in speakers as expected. Connection of a set of Bluetooth Headphones results in them being listed in the Play sound through list. The Test Sound button works through these headphones as does the output of the Rhythm Box Music Player. If a pair of wired headphones are plugged into the headphone socket, they are not deteted and the Test Sound button sends its test signal via the internal speakers. However, if the Bluetooth headphones are selected in the Play sound through list, the Test Sound button tests are directed through the Bluetooth headphones as one might expect. I am inclined to think that the original HDMI output was a red herring. I have, in the past, got sound to play through the speakers built-in to an HDMI monitor by connecting the monitor through the video output using an HDMI adapter. It seems that the sound output system is not very good at detecting which output devices are connected at any one time. This might be due to shortcomings in the kernel or for other reasons. Who knows? One thing that I can be sure of is that, after restarting the laptop, the sound system might well be in a new state and not necessarily in the one that it was in before restarting. There does not appear to be any consistent behaviour as yet. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1402194 Title: PCI/internal sound card not detected Status in alsa-driver package in Ubuntu: Incomplete Bug description: This bug relates to the internal sound hardware in a Dell XPS 13 laptop.
